Neijiang Container House Construction

Neijiang container house construction, centered around prefabricated steel structures, offers advantages such as personalized customization, rapid delivery, and environmental protection and energy efficiency. It is widely applied in fields including construction site housing, commercial facilities, and cultural tourism projects.

1. Construction Mode and Technical Features

Neijiang container houses primarily adopt prefabricated steel structure construction technology, with standardized components (such as wall panels, stairs, and steel structural frames) prefabricated in factories and quickly assembled on-site to complete the building structure. Taking Sichuan Lvjian Hangxiao Steel Structure Co., Ltd. as an example, its production workshop processes steel plates into various steel structural components through processes such as assembly, rivet welding, and shot blasting and polishing, which are then transported to the construction site for assembly. Such buildings are characterized by light weight, high strength, strong earthquake resistance (up to magnitude 7), and fast construction speed (a small building can be constructed in 3 days). Moreover, the entire process generates no dust and low noise, meeting green building standards.

2. Application Scenarios and Product Types

1. Construction Site Housing: Foldable containers, packing-box units, and color-steel houses are mainstream choices. For example, the foldable houses provided by Futongyuan Integrated Housing are fire-resistant, wind-resistant, and leak-proof, can be folded repeatedly 500 times, reduce transportation costs by 5 times compared to traditional containers, can be loaded with 6 sets on a 6-meter vehicle, and 20 sets on a 17.5-meter flatbed truck.
2. Commercial and Cultural Tourism Facilities: Demand for customized products such as internet-famous containers, mobile sales kiosks, cafes, and bed-and-breakfasts is increasing. The foldable containers from Sichuan Kuaizhu Integrated Housing Co., Ltd. adopt a V-shaped male-female interlocking design to solve leakage problems, can be unfolded by a single person in 5 minutes, and have a service life of over 20 years.
3. Public Facilities: Including mobile toilets, garbage rooms, duty rooms, and sentry boxes, full-size customization is supported. The main structures adopt hot-dip galvanized light steel frames or 304 stainless steel frames to adapt to different scenarios.

3. Policy Support and Industrial Foundation

Neijiang City has issued the Implementation Plan for Further Improving the Prefabricated Construction Level of Construction Projects, specifying that the proportion of prefabricated buildings in newly constructed buildings should be no less than 35% by 2025 and increased to 40% by 2026, with the prefabrication rate of government-invested projects required to reach over 50%. Currently, Neijiang has formed 3 large-scale prefabricated building production bases, with an annual production capacity meeting the construction demand of over 2 million square meters. The total area of newly started prefabricated buildings in the past three years has reached 3.678 million square meters.

4. Customized Services and Industrial Chain

Companies such as Jinhua Xin'an Steel Structure Engineering Co., Ltd. and Sichuan Jinzhu Kaiyue Construction Engineering Co., Ltd. provide one-stop services including design, production, sales, and installation, supporting personalized customization plans. The industrial chain covers steel structure production, modular design, intelligent construction technology, and after-sales service. Some companies hold multiple technical patents (such as 13 software copyrights and 38 utility model technologies of Sichuan Kuaizhu Integrated Housing Co., Ltd.), ensuring product quality and delivery stability.
